Detection of brain abnormalities following mild
traumatic brain injury (mTBI) is hard since tissue changes are subtle and
heterogeneously located, thus not well suited to be detected using group
analyses. We study a diagnosis approach in which free-water corrected
diffusion MRIs of acute mTBI subjects are individually compared to a
normative atlas. By analyzing the distribution of z-scores we are able to
demonstrate significant group differences, which were not detected using
conventional group analyses. We locate ranges in the distribution that are
most specific to the injury, and these infer the types of abnormalities that
can be expected in mTBI,
